The gravy covered boon thread inspired this! 
I was in Ikea once in the cafe and a lady loaded a tray with food for her and her DCs and (I presume DH.) she turned away with the tray loaded with food and promptly tripped over one of her very young DCs, the tray flew out of hands and the plates, drinks, everything shattered and left such a mess. Crowded restaurant and everyone stopped talking and stared! Poor woman!
Has anyone else ever cringed on another's behalf?
